摘要
本文集中研究全球环保５００佳－中国皖北小张庄生态村土壤环境质量。在系统的土壤元素地球化学采样的基础上，我们选取２５种元素（包括常量和微量元素）进行了土壤化学分析，建立了该区的土壤元素背景值。通过和邻区相同地貌单元的土壤样品的对比分析，根据Ｎｅｍｅｒｏｗ，计算了邻区土壤单元元素的污染指数和综合污染指数。最后得出结论：小张庄良好的生态环境有效并成功地保持了土壤的净化，防止了土壤的污染。
The paper focused on the soil environmental quality in a typical eco-village-Xiaozhangzhuang village awarded by the UNEP with the title of 'the Globale 500' in 1992. Based on the systematic sampling of elemental geochemistry on the soil and analysis of more than 20 elements including the major and trace elements, the element background values of soil have been established. By comparing with the soil quality in the adjacent area of the same morphological unit as that of Xiaozhangzhuang eco-village. With the element background values in Xiaozhangzhuang, the polluted index of single element and multiple index in the adjacent area according to Nemerow's method has been calculated, which is the first scientific assessment on the soil environmental quality in Xiaozhangzhuang ecovillage, the authors present the fact that the good eco-environment has the function of keeping from and purifing the soil pollution.
